Renwick succeeds Col. David Augustine, who announced last month he was retiring because of a medical issue that prevents him from flying. The announcement came 17 days after Umbarger said an investigation had cleared Augustine of allegations he had misspent taxpayer money or committed other improprieties.

Renwick is rated as a command pilot with more than 3,000 total hours and 148 combat hours. The Marshall, Illinois, resident, currently serves as the vice commander of the 181st Intelligence Wing headquartered in Terre Haute. He also has commanded maintenance and air support operations squadrons.
